Eco-innovation is quickly gaining traction to achieve the goal of long-term sustainability in the built environment. This is due to its capacity to reduce the environmental impacts of our production modes, improve nature's resistance to environmental challenges, and achieve more efficient and responsible use of natural resources while building infrastructure. This study used bibliometric analysis and systematic literature review to assess current state research on eco-innovation in the built environment to identify established and emerging research subjects for future study. The systematic research review we used in our study has not been grasped or assessed by other researchers on this topic. Firstly, based on our methodology, the systematic review identified 84 publications raised from scientific journals, including literature from 2012. Twenty-six publications were used after inclusion criteria were followed. According to our findings, 2021 produced the most articles and citations. China is the leader in publications and citations, and eco-innovation research in the built environment can be classified into five clusters. The research identified various limits that may allow new academics and practitioners to investigate Eco-innovation in new ways. Because most practitioners and policymakers are unfamiliar with this form of research, many remain theatrical and conceptual. Instead of focusing solely on opinion, future studies should focus on practical applications.
